Informative Video Before LMWH Postpartum - Randomized Controlled Trial

This single-center randomized controlled trial evaluates whether a short informative video can reduce anxiety and pain before the first postpartum administration of low molecular weight heparin (LMWH, Clexane). Eligible women will be randomized to receive either standard explanation alone or standard explanation plus a short educational video. The primary outcome is anxiety level assessed via the State-Trait Anxiety Inventory (STAI). Secondary outcomes include pain, satisfaction, and treatment adherence.
